[Coronary anastomosis. Angiographic study and statistical correlation in 140 patients with angiogenic coronary...

A great number of studies devoted to coronary artery anastomoses on the experimental animal or on post-mortem material, while the in vivo studies are relatively rare. The results of these studies are often contradictory, and many questions are still unresolved concerning the part played by the anastomoses in natural history of coronary artery atheroma. On 140 patients, all suffering from angina due to coronary atheroma, a study of the anastomoses visible on coronary arteriograms was undertaken, together with a statistical analysis of the various correlations between the presence or not of coronary artery anastomoses and the various criteria, anatomical, clinical and electrocardiographic.
